rspec users - Jan 2010 - unable to describe...expected?

Question.
I noticed that this code:

class Redcar::Project
  describe FileMirror do

is allowed, however this code

module Redcar
 describe Project do
    ...


is not.
Is this expected?

Oops--appears the problem was that I was running it as ruby instead of
spec (and/or including autorun).  Sorry for the noise.
